Some times radiometric dating produces impossible results.Uranium-Thorium-Lead Method Ages" in Billions of Years Some soil from the Moon has been dated as more than a billion years older than the uniformitarian age for the Moon.How a rock is formed is important to understanding its isotopic make-up and any dates derived.
Some rocks dated older than the 4.5 billion year evolutionary age for Earth. Isochron dating can also produce negative ages, by producing a negative slope.
During natural radioactive decay, not all atoms of an element are instantaneously changed to atoms of another element.
The decay process takes time and there is value in being able to express the rate at which a process occurs.
If the standard is of historically known age, such as would likely be used for testing Ar-Ar dating on sample of known age, then one would be more likely to get the correct age.
For allegedly older samples K-Ar is used to "date" the standard and as such it still has the same problems as K-Ar dating.
